After testing reveal salmonella and E. coli contamination, medical marijuana is recalled.


Due to contamination with germs, mildew, and pesticides, some jurisdictions have issued recalls of legal marijuana. State-by-state cannabis testing laws differ and might not be regulated, according to an expert. This may result in inconsistent cannabis quality and the distribution to medical patients of potentially hazardous goods. You should read Morning Brew too—over 3 million people do. Nearly 100 medicinal cannabis items, including flower, concentrates, cartridges, and pre-rolled joints, have been classified as recalled in Oklahoma , highlighting the disparity in state cannabis market legislation.

When verifying results from a state-licensed laboratory, officials from the state discovered prohibited levels of mold, pesticides, and germs like E. coli and salmonella.

In 2018, medical marijuana became legal in Oklahoma . Oklahoma, like the majority of other states with legal cannabis markets, mandates that all marijuana products cultivated or processed within the state undergo fungus, bacterium, and pesticide testing at an accredited lab.

According to Milan Patel, CEO and co-founder of molecular testing firm PathogenDx, other common tests take into account the potency of the cannabis (based on the THC and CBD content), potential heavy metal contamination, and the quantity of moisture retained in the product.

According to Patel, testing requirements differ from state to state, particularly between those that have developed regulated recreational markets, like Colorado or California, and those that are only beginning to offer access to medical marijuana.

Ones that have really well-thought-out restrictions and other states that haven’t really set a limit apart, he claimed.

The “loopholes” in the laws in states like Oklahoma and Arizona, where Patel works, might lead to contaminated products getting into the hands of medical cannabis users, many of whom have illnesses that make them more susceptible to disease.

CANNABIS TAINTED WITH MOLD HAS CAUSED SICKNESS IN SOME PEOPLE As part of a “secret shopper” program, state regulators probably started re-testing medical marijuana, according to Patel. Some states have started buying samples of medical or recreational marijuana and testing them at different labs to verify their results in order to make sure approved labs are up to pace.

Other times, widespread recalls and testing have been spurred by sickness outbreaks linked to legal marijuana. According to MLive, Viridis Labs studied marijuana consumption in Michigan last year and found that At least 18 people got sick after consumption resulted in reactions ranging from severe hospitalizations to minor allergy symptoms.

The Marijuana Regulatory Agency of the state recalled approximately 64,000 pounds of cannabis flower for additional testing in November 2021. Although the government withheld the quantity of the product that was found to be tainted, they did admit that many samples tested positive for aspergillus, E. coli, and salmonella.

Less than a month after the recall was issued, lawyers for Viridis Labs reversed a portion of it, allowing potentially contaminated cannabis to be sold again, according to MLive.

Aspergillus and related organisms provide a higher risk of lung infection when identified in cannabis flower, according to Patel, because so many individuals use cannabis for smoking. You “don’t want to take that chance,” he said, while policing medicinal marketplaces where a lot of customers have weakened immune systems.
